MILWAUKEE – The champion went to work on his game plan immediately in the fight – but that just meant the challenger had to bide his time.

Anthony Pettis survived champ Benson Henderson’s early clinch work against the cage, and then he went to work, himself. Pettis landed kick after kick to Henderson’s rib cage, and when the fight hit the canvas, he latched onto the champion’s right arm.

From there, the finish was quick – and surprising, because Henderson didn’t tap. He had to verbally submit to the armbar with 29 seconds left in the first – and the UFC had a new lightweight champion who got it done in front of his hometown crowd.

The lightweight title bout was the main event of today’s UFC 164 event at Milwaukee’s Bradley Center. It aired on pay-per-view following prelims on FOX Sports 1 and Facebook.

Henderson pressured Pettis right away and drove in to push him against the cage. The champion went after a single-leg takedown and worked to try to trip Pettis to the canvas. Eventually, Pettis worked his leg free to put the fight back to the center.

Henderson again came inside with a left hand and went after a takedown. But again, the hometown favorite defended – but ate an uppercut on the way out. Henderson went right back to the clinch, where he kicked at Pettis’ calves.

With about 90 seconds left, Pettis landed a solid right kick to the body for his best strike of the round, then came back with five more to the same spot.

With a minute left, Pettis tried one of his “Showtime”-style moves, but Henderson put him on his back. And that would prove to be his undoing. Once there, Pettis quickly worked for an armbar – and that was it. The official time of the stoppage was 4:31 of the first round.

Pettis’ road to the UFC lightweight title was a rocky one. He took Henderson’s WEC title in that promotion’s final event in 2010. Henderson, of course, went on to win the belt in the UFC and defended it three times. But Pettis had to work through a loss to Clay Guida to eventually regain the top contender spot – only to decide to drop to featherweight to challenge Jose Aldo.

That fight never took place earlier this month thanks to a short-lived Pettis injury. Instead, T.J. Grant, Henderson’s original challenger, had to pull out of the title fight – and Pettis got his shot, and a shot in front of his home fans in Milwaukee.

“When I had to pull out against Jose Aldo, my dreams were crushed,” Pettis said. “I thought I was never going to get a title shot. But you can’t write a better story.”

Maybe you can, though – and maybe Pettis already is trying to do that. He was quick to call out featherweight champ Aldo, saying the two should pick which belt to fight for and meet for a title.

Henderson, who kept his right arm inside his shirt after the fight, said he’ll work his way back.

“I’ll be back, don’t worry about that,” Henderson said. “Anthony’s a tough dude. He proved himself to be the No. 1 contender, and proved himself to be the champ. He got my arm … with a high-level armbar. The strategy was to put pressure on him – he’s not as good going backward. The kicks he hit me with that were pretty good were while he was coming forward.”

Pettis (17-2 MMA, 4-1 UFC) ran his winning streak to four fights with the victory and has his second win over Henderson. Henderson (19-3 MMA, 7-1 UFC) had a seven-fight winning streak snapped.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
